Looking for a person who has experience or knowledge of pipes to write a 2-3 pages essay. I I need an essay about corrosion of PVC and Ductile pipes researched by doctors and professors or companies including as much data on corrosion of that pipe of that specific pipe along with calculations or how to fix that corrosion problem. Along with uses of the pipe. It would great if a person can provide pictures such as CAD with how it corrodes and how it can be fixed.

NOTE: WE ARE ONLY LOOKING FOR FREELANCERS IN THE SAN FRANCISCO BAY AREA. The full description for the job can be found in the attached PDF. Note that the budget posted here and the quote we are looking for is for having our current needs met. Those needs are to: incorporate control of pneumatic control valves into our current electronics box which is composed of a couple adafruit and sparkfun breakout boards with an Arduino; find and incorporate a way to sense the orientation of our device; and modify code so that we have better filtering of speed data coming from the truck, a stall feature that is suitable for the pneumatics system, and better user interface. To get a better idea of what we are doing, check out our website: www.xstreamtrucking.com

Looking for someone who can respond to the following question below. Responses to the questions should be based on the scenario given. Consider some discounting problems. a. What is the present value of a $100m loss from an environmental catastrophe, 100 years in the future, if the discount rate is 2%? (You can choose your own rate of compounding.) b. What is the present value of the same loss, if the discount rate is 1.5% because of lower growth rate trends? If 1%? c. If a policy analyst is not certain which of the discount rates is appropriate, but believes there is an approximately equal chance of each outcome, is the average discounted present value appropriate? Does that imply a higher or lower discounted value than just using the average discount rate? d. Suppose the best available models imply a link between discount rate and damages: if economic growth is slow then the damages would be $150m and the appropriate discount rate would be 1%; if economic growth is middling then damages would be $125m and a discount rate of 1.5% would turn out to be most appropriate; if growth is good then damages are $100m and the rate 2%. Carefully explain whether averaging is the best policy (you might cite readings on this topic). What is the present value of the loss in each case?

Looking for someone who can respond to the following question below. Responses to the questions should be based on the scenario given. Consider a firm that emits CO2 in its production of output, and it faces a new regulation that requires it to buy emissions permits for each unit of CO2 produced. For simplicity assume that it emits one unit of emission (e) for each unit of output produced. Its cost function, before the emissions permit rules are passed, is c(y)=10+5y+y^2. Suppose P=20. a. How much would the firm be producing, before the emissions permit rules? Explain. b. How much CO2 would it be producing before the rules went into effect? Explain. c. Suppose each permit cost $6, how many permits would the firm choose to purchase. Explain. d. What if permits were just $3? If they were $10? e. Would you predict any changes to the price of the output? Explain how and why this might come about.

Looking for someone who can respond to the following question below. Responses to the questions should be based on the scenario given. Consider an industry that creates pollution. Demand for the product is given as P = 150 – 2Q. Supply (considering just private costs) is P=Q. Suppose that production creates a marginal external cost of MEC = Q additionally. a. What is the unregulated equilibrium value of production? b. What is consumer surplus and producer surplus in the unregulated market? c. What is the deadweight loss from unregulated production? d. What is the socially optimal level of production? e. Explain why a "free market" fails in this case. f. Suppose a tax were imposed of T=$8, what would then be the deadweight loss? g. Is there some level of tax that would eliminate the deadweight loss? What value? h. Suppose that there is an unregulated fringe market, that can produce additional output at a price of $60 (there may be a variety of reasons for the lack of regulation, such as point vs nonpoint air pollution sources). What is the deadweight loss of the tax from the previous question?
